Bro,
i assume you are new here so i would advise you to go through the announcements section first.
I think it could have been from his ICE set up unless you are talking specifically about the engine making the noise.

And if it wasn't the booming of an ice setup that you are talking about, then maybe it was the vrooming from a modified exhaust system. Mufflers/catback exhausts/free flow systems are a common sight nowadays, susprised how you haven't come across any of this earlier.
following link for automech exhausts should help you understand what i am talking about just incase you are not familiar with the same.

you can even go through the modifications section as this topic has been extrensively discussed on the forum.
